Switching device and method of controlling switching device |
摘要 |
A switching device is disclosed in which electric current through a rectification circuit, depending on whether a main switching element turns on or off, and thus electric current from the rectification circuit flows through whichever of first and second sub-switching elements, turns on. By controlling the turning on and off of the first and second sub-switching elements, the switching is performed which determines through which of the first and second output circuits the electric current from the rectification circuit flows. Thus, a voltage that is a result of transforming a voltage from a DC power supply in response to the electric current flowing through the first output circuit, is output from a first output terminal, and a voltage that is a result of transforming a voltage from the DC power supply in response to the electric current flowing through the second output circuit, is output from a second output terminal. |

1. A switching device comprising:
a main switching element capable of switching a voltage input from a DC power supply; a rectification circuit with a coil, connected to the main switching element; a first output circuit including a first sub-switching element performing switching between the rectification circuit and a first output terminal, with one end of the first output circuit being connected to the rectification circuit and the other end to the first output terminal; and a second output circuit including a second sub-switching element performing switching between the rectification circuit and a second output terminal, with one end of the second output circuit being connected to the rectification circuit and the other end to the second output terminal. |
